2 Claims. (cine- 174) This invention relates to a new and improved adjustable stopof the character described for use primarily in connection with the prefabrication onstructural building units. ,p j "An object'of the invention is to provide a stop of thecharacter describedwhich'is 'of rugged and sturdy construction, which may be, readily and cheaply manufactured andwhic'h' is adapted ,for 'usefin connection with .a suitableabutment member to proyide a fixed, rigid, s"turdy strucelementswhich are to Oth j pbjects 'of'the invention are to provide such a stop 'whichiis adjustable in connection *wjith aid abutment member; t0 provide' su ch a t I a providing two metallic gripping sur aces adapted 1 to engage "saidabutmente1ement;jat least one of said surfaces being" forined of. a relatiyelyfsoft metal 'havingfa, igh coefficient of friction'withrespect 'to said abutment elementi c 'Ot h'er objee'tsof theinventionwill in vpartbe obvious and will 'n'part appear hereinafter.

nvention,ac ordin ly (compri n a ticle of aufacture,possessinglthefeatures, prop erties' andthe relation of element'swhich will be exemplified, in the'article hereinafter described and. thes'tjopeof'the application of which will be indicated in'the claims.

For a fuller understanding "of l i nature: and

lobj'ectsof theinvention, reference should be had tov the following (1 tailed description,'taken in connection with 'the' accompanying drawing, in which:

,Figure lis a plan'view of I a device embodying I ,oneform of the invention in engagement with a suitable abutment element, portionsfof the device being shown-in dotted lines for clearness;

Fig, 2, is a view in section abutment element and aiportion of a supporting stable, along the line 2,2 in Fig. 1; and I I Fig. 3. is. a ,view in section of. a modified form ;of stop, showing theplug-equipped face of the slot-providing means therein, f

' There has'been a demand, particularly in connection with, the manufacture of .prefabricated housing units, for a rugged, sturdy, easily adjusted stop which maybe employed with a suitable abutment element .support against which structural elements such as studs, joists, rafters, doors, floor boards and the like may be positioned before being sawn to predetermined lengths. It will be apparent that where the structural elements are particularlyheavy, the stop and abutment element are subof the device, the I v .ingly it has'been found for jected to a severe battering. Where the stop is adjustable along the abutment element, and this condition is preferred, it has been found that frequently the stop slips and fails to hold against the severe treatment it must receive. Accordmany :st'uds are to be cut to predetermined lengths, slippage of the stop along the abutment element rnayresult in a difference in the length of the first cut stud andthose cut at a considerably'later period, for as the stop slips on the abutment, the stud length increases.

This invention contemplates the provision of I arugged, sturdy stop which may be readily adjust'ed along a suitable 'abutment'element and which, when clamped in position upon the abutment element, remains in that position despite the hammering and battering to which such a i stop must be subjected.

. the element whichlies adjacent to the abutment face or the member to provide an angular X One embodiment of the invention is shown-in the drawing w'herein l0 represents any suitable supporting table upon which there may be bolted or otherwise affixed an abutment element 12 which, as shown in the drawing, may be in the form of an angle iron, the upright portion 14 of the angle iron serving as an abutment against which structural elements may be positioned.

The adjustable stop may comprise two relatively heavy members l6 and I8 aflixed 'in spaced and substantially parallel relation to a plate 20, for example by means of the bolts 22.

As shownparticularly inFig. 2, this construc- .tion provides a. heavy, narrow, inverted, U- shaped structure, the'space between the elements IE and IBprovidingare'cess for the reception of the upright portion I4 of the abutment member 12 and the plate 20 resting upon the upper edge of the portion M of theabutment member l2, so

that the stop straddles the abutment member loosely. The inner faces of the elements [6,18 are preferably substantially parallel with" the sides of theupright portion M of the abutment member l2 A recess 24 isv provided in the inner face of either element I6, or l8.. As shown in the dravvingthis'recess is provided in element l8,

l4, and this is a preferred condition for ease in manipulating and adjusting "the stop, I

The elements [6, l8 and 20 are preferably of hard metal, for example iron or steel. An adjustable plug of a softer metal, for example brass,

is positioned 'within'the recess 24 in the element I8 and is slidably mounted therein so that it may be moved toward and away from the abutment example that where preferably 1 Adjustment of this set screw 28 position, if properly adjusted, for long periods of time. It will not slip along the abutment element. It is resistant to hard wear and abusive usage and provides a tool of great utility especially where, as has already been pointed out, it is to be employed in connection with the prefabrication of a I great many elements of standard lengths.

It will, of course, be understood that while the .particularconstruction10f the stop shown in the drawing and describedin the specification is pre-- ferred, this construction may be altered or modi- When the set screw 28 is turned inwardly, for c ing the soft metal plug 26 against the upright;por tion M of the element I2, clamping action takes place between the plug 26 and fthe elemeht t5,

While the surface of contact between the soft metal element 26 and the zuprightportion ll of the abutment element I2 is the to ht portion vlate-her; coefiicient of friction firmly r ns; the .surtace of th p ight-portion M and slip age ofth step along the abutment element is prevented, en though "the .st-op Jae sub; acted .to sever 11am not so large as the surface of contact between the element 16 and M, lthe softer metal withits died in many ways which will be apparent to those -wskilled in the art without departing from the scope of the invention.
